Almost all 60Hz AC buzzing is caused by earthing loops and acts like a radio antenna (ring antenna). The buzzing noise canceller completely eliminates this by disconnecting the grounding circuit, making the signal line unable to absorb the AC buzzing and noise first. Compared with balanced circuits, unbalanced circuits are more susceptible to current noise and RF interference, the longer the unbalanced cables are, the more likely problems are. Using this device to connect two devices is one of the most economical and effective methods to convert between unbalanced signal and real balanced signal. Automatically convert signal voltage to match ground potential difference.
